The photocontrol of the functional coupling between photosynthesis and stomatal conductance in the leaf was investigated in gas exchange experiments using monochromatic light provided by lasers. Net photosynthesis and stomatal conductance were measured in attached leaves of Malva parviflora L. as a function of photon irradiance at 457.9 and 640.0 nanometers.Photosynthetic rates and quantum yields of photosynthesis were higher under red light than under blue, on an absorbed or incident basis…

Rapid and Specific Modulation of Stomatal Conductance by Blue Light in Ivy (Hedera helix) : An Approach to Assess the Stomatal Limitation of Carbon Assimilation.

The results indicate that significant stomatal limitation of assimilation can occur, but that this limitation may improve water use efficiency under high VPD conditions.

The magnitude of blue-light-specific stomatal opening appears to be sensitive to environmental conditions that affect the carbon and water status of the plant.

Dual beam experiments provide a suitable experimental approach to study the blue light mechanism for stomatal regulation in the intact leaf to enhance the response to blue light and saturated the photosynthesis dependent mechanisms.

Phototropins But Not Cryptochromes Mediate the Blue Light-Specific Promotion of Stomatal Conductance, While Both Enhance Photosynthesis and Transpiration under Full Sunlight12[C][W][OA]

It is concluded that considering their effects at high irradiances cry and phot are critical for the control of transpiration and photosynthesis rates in the field.

Metabolic energy for stomatal opening. Roles of photophosphorylation and oxidative phosphorylation

Light-dependent stomatal opening appears to require photophosphorylation from guard-cell chloroplasts and the activation of the blue-light photosystem which could rely either on oxidative phosphorylation or a specific, membrane-bound electron-transport carrier.

Red/blue light ratio strongly affects steady-state photosynthesis, but hardly affects photosynthetic induction in tomato (Solanum lycopersicum).

It is concluded that varying red/blue light ratios during growth and measurement strongly affects steady-state photosynthesis, but has limited effects on photosynthetic induction rate.

Stomatal Limitation to Carbon Gain in Paphiopedilum sp. (Orchidaceae) and Its Reversal by Blue Light.

Blue light enrichment resulted in significantly higher growth rates-of up to 77%-over a 3 to 4 week growing period, with all evidence indicating that the blue light effect was a stomatal response.

Stomatal responses to light in the facultative Crassulacean acid metabolism species, Portulacaria afra

Results indicate that P. afra does possess typical guard cell responses to light when performing C3 metabolism, and the metabolic pathways mediating these responses are either lost or inhibited when CAM is induced.



Effect of Light Quality on Stomatal Opening in Leaves of Xanthium strumarium L.

Determination of flux response curves on leaves in the normal position or in the inverted position led to the conclusion that the photoreceptors for blue as well as for red light are located on or near the surfaces of the leaves; presumably they are in the guard cells themselves.

The Blue Light Response of Stomata and the Green Vacuolar Fluorescence of Guard Cells

Guard cells modulate gas exchange between the leaf and the environment by regulating the aperture of the stomatal pore. The changes in aperture are mediated by fluctuations in the turgor of the guard

Separation and measurement of direct and indirect effects of light on stomata.

Stomata responded to light even in leaves whose net exchange of CO(2) was reduced to zero through application of the inhibitor of photosynthetic electron transport, cyanazine (2-chloro-4[1-cyano-1-methylethylamino]-6-ethylamino-S-triazine).


Study on the 3-(3,4-dichlorophenyl)-1,1-dimethylurea-sensitive variable fluorescence kinetics of uncontaminated epidermal peels of C. comosum indicated that guard cell chloroplasts operate a normal, photosystem II-dependent, linear electron transport.

Stomatal conductance correlates with photosynthetic capacity

Previous studies on the Physiology of stomata in higher plants suggest that stomata influence the rate of CO2 fixation in leaf mesophyll tissue. We believe that an equally important stomatal function

Action Spectra for Guard Cell Rb Uptake and Stomatal Opening in Vivia faba.

In the abaxial surface of leaf discs under air of normal CO(2) concentration, stomatal opening in white light approached its maximum at an intensity similar to that for epidermal strips, and at both quantum flux densities, the action spectra for opening in leaf discs were very similar to those for epidersmal strips.

Observations constitute the first specific evidence of a guard cell chloroplast response to CO(2) and may provide a mechanism regulating the availability of high energy equivalents at the guard cell plasmalemma, thus affecting stomatal opening.

Stomatal response to environment and a possible interrelation between stomatal effects on transpiration and CO2 assimilation

Abstract It had been hypothesized that if daily CO2 assimilation is to be maximized at a given level of daily transpiration, stomatal apertures should change during the day so that the gain ratio
